LOCK.

Specification of Letters Patent.

Patented Aug. 2, 1910.

Application filed March 16, 1910. Serial No. 549,616.

To all whom it may concern:

Be it known that I, HANSFOBD C. STEvENs, a citizen of the United States,and a resident of F lemington, in the county of Taylor and State of WestVirginia, have invented certain new and useful Improvements in Locks, ofwhich the following is a specification.

This invention is an improvement in looks and especially in the class ofhasp locks such as are particularly adapted for use in fastening trunks,dress suit cases and the like; and the invention consists in certainnovel constructions and combinations of parts as will be hereinafterdescribed and claimed.

In the drawing Figure 1 is a front elevation of my look as in use. Fig.2 is a cross section on about line 2-2 of Fig. 1. Fig. 8is a crosssection on about line 33 of Fig. 1. Fig. 4 is a detail top plan view ofthe rotary tumbler. Fig. 5 is a detail perspective view of the undersideof the knob and Fig. 6 is a detail top plan view of the case with thelatch in place, the hub being shown in section.

While in Figs. 1 and 2 the lock is shown as mortised or recessed intothe body of the trunk, it is manifest it may be mortised into the lidwithout departing from the principles of my invention.

In the construction shown the bolt A is mounted on the trunk body B andthe lock case C is carried on the swinging end of the hasp D which ispivoted at D to the trunk lid E and is actuated by a spring F outwardlyoff the bolt A when the latch devices presently described are released.This hasp D forms what may be termed a main frame or carrier at D forthe lock case C, but manifestly when the lock is used for other thantrunk or dress suit cases, the lock may be supported in any suitablemanner.

As shown, the lock case has a base plate C and a cylindrical flange Cand is provided at its center with a tubular hub Gr mounted on the baseplate and open at its inner end for the reception of the bolt A as shownin Figs. 2 and 3 and provided at its outer end with a cap G whichprojects at its edge G over and operates to retain the knob H upon thesaid hub.

Adjacent to the base plate C of the case C, I form the hub G with a slotG and through which the tongue I of the latch I lays into and out ofengagement-with the Bolt A. This latch I is pivoted at I to the baseplate G, is actuated by a spring J normally to the position shown inFigs. 2 and 6, in which it will engage in the notch A of the bolt A andat its free end the latch I underlies a keeper I which braces the latchin position for holding the bolt A as will be understood from Figs. 3and 6 of the drawing.

The latch I is adapted for engagement by the projecting pin K of theknob H, being in the construction shown provided with an opening I forsuch purpose, the said opening being formed to receive the end of thepin K when the latter has been forced through and beyond the rotarytumbler L presently described.

The rotary tumbler L has a base plate L which overlies the base plate Cof the casing C and also overlies the latch I and this tumbler L has acentral opening L fitting over and turning upon the hub G and is alsoprovided with a cylindrical flange L operating within the case andserving as a guide for the knob H as the latter is forced in and out inthe operation of the invention.

The knob H may be milled on its outer end at H to facilitate its turningas will be understood from Figs. 1 and 2 and this knob has a centralopening H to fit over the hub Gr and is provided on its inner side witha pin K provided at its inner end with a reduced extension K.

The base plate L of the tumbler L is provided with a number of openingsL any one of which is large enough to receive the reduced extension K ofthe knob pin K and the said plate L is provided also with a largeropening L adapted to receive the body of the pin K as will be understoodfrom Figs. 3, 4i and 5 of the drawing. The pin K is disposed on the knobH to enter any one of the circular series of holes L L The knob H ispressed outwardly to the position shown in Fig. 2 by a spring M bearingbetween the sald knob and the plate L of the tumbler and the said knobmay be depressed from the position shown in Fig. 2 to that shown in Fig.3 to cause the knob pin to project through the opening L of the tumblerL and with its extension K projecting into the opening I of the latch asshown in Fig. 3 so a proper turning of the knob will adjust the latch Iback from the position shown in full lines in Fig. 6 to that indicatedin dotted lines in the same figure in which the latch will release thebolt.

In carrying out the invention, I provide rounding the tubular hub andthe knob, the tumbler and the oasin with suitable graduations and theknob 1- tumbler and easing are arranged in such relation that when acertain combination is formed, the knob pin K will be directly over thelarger opening L of the tumbler and such opening L of the tumbler willbe di rectly over the opening I of the latch so a depression of the knobto the position shown in Fig. 3 will adjust the knob pin through thebase plate of the tumbler and into engagement with the latch to operatethe same as desired. Thus the bolt A may be released and the bolt isbeveled on its outer end at A so it will automatically adjust intolocked engagement with the latch I when the parts are forced together inthe position shown in Fig. 2.

In operation the knob may be readily turned, the combination beingknown, to bring its pin K into alinement with the opening L and the pinbe then depressed into the said opening L and the knob be turned withthe tumbler until the pin registers with the opening I of the latch, orif desired the knob may be depressed to brmg its reduced extension Kinto any one of the openings L of the tumbler and be operated to turnthe tumbler until its opening 1*- 1s alined with the opening I in thelatch and the knob be then released and then turned relatively to thetumbler L to bring the pin into alinement with the opening L andthe knobbe then depressed to force its pin into engagement with the latch when aturn1ng of the knob in the proper direction will throw the latch I outof the dotted line position shown in Fig. 6 and release the bolt.

As best shown in Fig. 2, the lock is mor tised or recessed into thetrunk, and as best shown in Figs. 2 and 3 a stop shoulder 1s provided onthe tubular hub to limit the mward movement of the knob.

The tubular hub cap piece does not extend above the hasp and the haspthus protects the look.

I claim:

1. The improvement in locks herein described consisting of the casehavmg a base plate provided with a cylindrical rim flange, a tubular hubmounted on the base plate and having a lateral opening adjacent thereto,a latch pivoted on the base plate and provided with a tongue movablethrough the open ng in the tubular hub into the same, a spring actuatingthe latch, a keeper on the base late and overlying the movable end ofthe etch to brace the same, the latch having an opening for thereception of an operating pin, a tumbler surrounding the tubular hub andhaving relatively large and small openings which may be brought intocoincidence with the opening in the latch, a knob suroverlying thetumbler, a spring pressing said knob outwardly away from the tumbler andan operating pin projecting from the knob toward the tumbler plate andhaving at its inner end a reduced extension, the body of the pin andsaid reduced extension being adapted respectively to the large and smallopenlngs of the tumbler, all substantially and for the purposes setforth.

2. In a lock, the combination with a casing having a base plate providedwith an opening and a tubular hub surrounding the same and having alateral opening in said hub adjacent to the base plate, a latch hav inga tongue movable into the-opening in said hub, a tumbler plate overlyingthe said latch and a spring actuated knob overlying the tumbler plateand having a latch operating pin adapted to project through the tumblerplate into engagement with the latch for operating the same, the tumblerplate having an opening for the passage of said pin, substantially asset forth.
